Framework for Recycling Foreign Spent Fuel(art. 8)
► Reinforcing the control of SF importation and waste shipping:
“[Spent fuel] introduction for treatment can be authorized only as part of
intergovernmental agreements and provided the radioactive wastes, resulting after the
treatment of these substances are not stored in France beyond a date set by said
agreements. The agreement states the estimated periods for the reception and treatment
of these substances and, where applicable, the prospects for the subsequent use of
radioactive materials separated during treatment.”
►Practical consequences:
New accounting system for RW
International agreements
Public reporting with detail description of :
Spent fuel and waste packages stockpiles and flows (including reprocessing
and shipping schedule)
Radioactive materials (U, Pu)+ Follow up of inter-governmental agreements

Why reprocess and recycle ?
2 - Reprocessing provides flexible solutions for the long
term : deployment of breeders, MA recycling, …
3 - Saves natural resources : 25 % of natural uranium to
day and avoid the use of it in the long term (with Breeders)
1 - Reprocessing makes waste management easier :
Reduces volume of ultimate HLW conditioned waste (factor 5 to 10)
Can reduce thermal load in final repositories ( lower size and cost)
Strongly reduces overall radiotoxic inventory (up to a factor 10)
Produces well characterized and qualified waste packages
Provides a reliable option for an interim long term storage period
… while protecting human beings and the environment
And for a cost less than 6 % of the cost of the KWh
This contributes to make nuclear energy MORE ACCEPTABLE to the public

RECYCLING SAVES NATURAL RESOURCES
Reprocessed uranium (RepU)
Represents about 95 % of the mass of LWRs spent fuel (enrichement 0.8 % to 0.9 %)
but mixed with U236
Its recycling (after re-enrichment) is already experienced by several utilities
throughout the world (in 2 PWRs in France, all RepU in the near future)
Recycling RepU allows to save between 11 % to 13 % of natural U
Plutonium
1 gram of Pu = 1 or 2 tons of oil
In France, all plutonium is recycled in MOX fuel :
roughly 10 tons/year = 12 % natural U saving (equivalence : 10 million tons of
oil, that is 10 % of imported oil)
A gain of a factor 50 or more could be
reached in the future with Gen-IV reactors
IAEA - INPRO meeting - International aspects of reprocessing and recycling - 4-7 octobre - D GRENECHE
To sum up …
Reprocessing / recycling option :
Recycles of the content of spent nuclear fuel
Conserves of our natural resources
Represents less than of the cost of the kWh
Divides waste volumes by (may be more in the future)
Divides waste toxicity by (but if recycled in LWR produces MAs)
Produces waste packages that remain stable for tens of thousands of years : that’s
ease SAFETY DEMONSTRATION of the final disposal of ultimate waste and make
the public more confident to this solution.
Reprocessing gives time and expands choices for the best
possible management of nuclear waste: FLEXIBILITY

USA : “Federal loan guarantees are not the most
important incentive needed to support construction
of new nuclear units. The most important issue to
address, to gain public support, is disposition of
spent fuel, and the answer is reprocessing and
recycling that fuel. Technology to do that could be
developed and implemented more rapidly than could
coal combustion technology using carbon capture
and storage” James Rogers, CEO Duke Energy
Recycling : international status
IAEA - INPRO meeting - International aspects of reprocessing and recycling - 4-7 octobre - D GRENECHE
Multinational Approaches to the fuel cycle :
an industrial point of view
Limitation principle and security / guarantees of supply
Long term contracts (but with suspension clauses)
Existence of competitors
Large size profitable facilities
Matched with governmental or international export agreements
Justification principle to allow evolution of capacities
No a priori prohibition of new capacities in new countries IF there is an
economic evidence of the need and IF non proliferation status of the country is
undisputable
Optimization concept
Existing capacities should be better used and preserved
Competition should be kept but financial incentives could be justified
Radiation Protection basic principles can be applied to multinational
approaches for the back-end of the fuel cycle
IAEA - INPRO meeting - International aspects of reprocessing and recycling - 4-7 octobre - D GRENECHE
Control Approach for nuclear materials
EURATOM : In implementation of the article 77 of the EURATOM treaty, the
Commission insure that :
The nuclear materials are not diverted from the declare use,
The respect of provisions about supplies and obligation towards states or international
organizations.

Transport of ultimate waste (“residues”) from reprocessing
Vitrified and compacted waste are
conditioned in the same universal
and multi purpose canister, named
the Universal Canister (UC) : easy
handling operations either by a
crane or by a loading/ unloading
machine.
The resulting residue is named:
CSD-V or UC-V for vitrified waste,
CSD-C or UC-C for compacted waste.
For the transport of the vitrified
residues, an IAEA type “B”
packaging is required.

General aspects – 1 : a stringent regulatory framework
The transport of radioactive material worldwide is governed by a very
stringent and demanding regulatory regime, which includes
standards, codes and regulations that have been continuously
revised and updated over the past four decades.
In addition to the safety regulations, the regulatory regime addresses
other related issues such as physical protection and liability.
IAEA regulations (first publication in 1961) is a common regulatory
basis for more 60 nations and most of international organizations
dealing with transportation
International Maritime Organization (IMO) has also introduced its own
international code and security rules, in particulars for ships and
containers
IAEA - INPRO meeting - International aspects of reprocessing and recycling - 4-7 octobre - D GRENECHE
General aspects – 2 : an international consensus
In September 1998 the General Conference of IAEA, which brings
together all the Member States of the Agency, recognised that
“compliance with regulations which take
account of the Agency’s Transport
Regulations
is providing a high level of safety during the
transport of radioactive material” (Resolution
GC(42)/RES/13).
IAEA - INPRO meeting - International aspects of reprocessing and recycling - 4-7 octobre - D GRENECHE
General aspects – 3 : technical aspects
All transported nuclear materials are in a solid form and are locked in
special casks
These casks are submitted to extreme accidental conditions tests
(drop, fire, immersion, …)
Sophisticate tracking systems are in force as well are emergency
plans and response teams
Transports are submitted to high safety and security standards
There has never been accident leading to significant radioactive
release in the past 50 years
IAEA - INPRO meeting - International aspects of reprocessing and recycling - 4-7 octobre - D GRENECHE
General aspects – 4 : social aspects
Transportation of nuclear materials (TNM) can be adversely affected by
oppositions from some resident countries (populations, media, or
governments) along shipping routes, in spite of the UNCLOS convention(1).
Industry stakeholders concerned (suppliers of recycling services, utilities, carriers,…) are
conscious of fears and concerns raised by TNM in these countries. Therefore,
they consider that it is their responsibility to inform them on this issue
As part of this effort, industry stakeholders have send representatives in these
countries to understand their preoccupations and to explain them safety and
security provisions of TNM, and to tackle further specialized issues
They have also undertake a program of visits of PNTL facilities and French
recycling plants (example : journalists and environmental association peoples were on board of
the “Pacific Swan” for the crossing of the panama canal in 1998). Number of information
means are also widely used (brochures, video, interviews,…)
(1) : The United Nations Convention on the Law of the Sea (UNCLOS) establishes rules governing all uses of the world's oceans,
seas, and their resources. It clearly establish that costal states have no right to deny passage to ships transporting nuclear materials

It complies with ISO 9001 and 14001 requirements.
The ships have safely covered more than 5 million miles and there has
never been a single incident resulting in the release of radioactivity
IAEA - INPRO meeting - International aspects of reprocessing and recycling - 4-7 octobre - D GRENECHE
International transports : some denials and delays(1)
Some shipping companies, air carriers and port terminals have policies
refusing to transport radioactive material (“Class 7”)
Impediment to transport only due to radioactive properties of the material for
transport
Possible reasons are

Conclusion on back-end of fuel cycle (1/2)
Many nuclear countries (and most of countries having a significant nuclear program) consider that RECYCLING is the best strategy for achieving a SUSTAINABLE nuclear energy (while avoiding spent fuel accumulation and buildup of “plutonium mines”)
Quite extensive industrial worldwide experience already exist on reprocessing and recycling : it is in particular a mature industry in France
Reprocessing makes waste management easier and safer, while keeping high standards of safety and quality as well as having very low environmental impact : this provides a steady back-end solution in France
The PUREX process used in France will dominate the world industrial reprocessing for next decades (including its variants such as COEXTM)
IAEA - INPRO meeting - International aspects of reprocessing and recycling - 4-7 octobre - D GRENECHE
Conclusion on back-end of fuel cycle (2/2)
R&D priorities should focus on new improvements of this process :
Further reduce its cost
Increase its flexibility (adaptation to new fuels, adaptation to innovative management of radionuclides, …)
Enhance its operating performances (maintenance, environmental impact, waste generation, …)
New requirements may appear in the near future :
Partitioning of MA (or even LLFP)
Intrinsic proliferation resistance constraints (no pure Pu separation)
R and D should also address these issues
R and D on future reactors (GEN IV) must be backed up with R and D on their associated fuel cycle
Industrial recycling facilities in France have already been used by foreign
customers and could meet additional needs along the lines of Multi-National
Approaches concepts.

To sump up, CLOSING the fuel cycle ….…has been always viewed in France as a national interest driven issue by policy makers and industrial actors
…is an industrial reality with more than 25000 tons of LWR fuel reprocessed more than 100 tons of plutonium recycled in France
…meets highest safety and environmental standards and features outstanding records in this area
…has clearly been proven a cost effective solution for spent fuel management while being a flexible way to cope with future challenges
… has been largely and successfully implemented on a multinational basis, proving the feasibility of this approach for the back-end of the fuel cycle, as promoted by IAEA
CLOSING THE FUEL CYCLE ENABLES TO EXPLOIT ALL ENVIRONEMENTAL ASSETS OF NUCLEAR ENERGY AND HELPS MAKING THE CONCEPT OF SUSTAINABLE ENERGY A REALITY

The role of recycling in assets and challenges of nuclear energy
Assets of Nuclear Energy
Competitiveness
Security of supplies (mainly national industry)
Minimal impact on environment
NO GREENHOUSE GAS EMISSIONS
Challenges (sustainability criteria for Nuclear Energy)
Long term availability of uranium Breeder reactors + recycling
Waste management recycling (+ P&T ?)
Non proliferation Multinational approach for fuel cycle services (IAEA, GNEP,
International fuel cycle centers, …) + efficient institutional and international
control regimes (safeguards, NSG, …) + plutonium control (no “plutonium
mines”) and degradation (Pu in spent MOX fuel = non weapon usable)
FUEL CYCLE back-end plays a fundamental
role to cope with these challenges

"let me remind you of the fact that light water reactors, such as AREVA’s
EPR, present absolutely no risk in themselves as far as proliferation is
concerned. As for the nuclear material needed to operate such reactors, it
may become sensitive only when associated with the mastering of highly
sophisticated dual-use technologies, namely uranium enrichment and
spent-fuel treatment. But most countries do enjoy the benefits of nuclear
energy without having to master those technologies : thanks to a well-
functioning fuel-cycle market, with suppliers like AREVA that provide
enrichment and spent fuel management services at competitive prices,
they simply do not need it"
Multinational Approaches to the fuel cycleassessing the proliferation threat
4 Challenges
1. No diversion of nuclear material under safeguards to undeclared illicit uses
2. Absence of undeclared (ie clandestine) facilities, through the use of imported
technology or equipments or through purely national developments
3. No theft of weapons grade material or weapons from the military stockpiles
4. No use of civil facilities, equipments and materials for weapons fabrication in
case of withdrawal from NPT
Fuel cycle concerns
Sensitive facilities and material can be properly safeguarded (up to now,
there is no case of diversion and misuse of safeguarded material )
BUT
No guarantee upon use of sensitive facilities after withdrawal from NPT

Conclusion on non proliferation concerns (industrial approach) - 1/2
Nuclear industry is an important stakeholder in the non proliferation debate
Proliferation issue serves as argument against the use of nuclear power and development of industry
Support or acceptance of public opinion is needed
Non proliferation is part of ethical rules and sustainable development
Industry has a major role as a designer of nuclear facilities, a sensitive material holder, a supplier of surveillance and safeguards equipment, an exporter of material, equipment and technology
Industry can contribute to counter proliferation efforts by securing material from the military sector
IAEA - INPRO meeting - International aspects of reprocessing and recycling - 4-7 octobre - D GRENECHE
Conclusion on non proliferation concerns (industrial approach) - 2/2
A strong institutional non proliferation framework is already in place in France through :
International safeguards
France, as a signatory of NPT is under IAEA and EURATOM safeguards + additional protocol regime (ratified by France)
Export control procedures
As a member of Nuclear Supplier Group, France follows closely its guidelines (i.e; very stringent conditions for the export of sensitive technologies or nuclear materials)
Bi lateral agreements are also implemented (ex. with Japan)
IAEA conventions
Physical Protection, safety, waste management.
